@Felthry It's bothered me intermittently since someone pointed it out when I was Like Eight.
@Austin_Dern (to possibly clear up some of that bother: consider that, if no one can tell, that would mean it can't have had any effect, adverse or otherwise)
@Austin_Dern I think it's not that the concept makes sense, but that the concept can't be imagined because you can't imagine anything on the scale of an entire universe. You always think of an outside, which, as far as science is aware, doesn't exist
the concept of "literally everything" is difficult to grasp, so any conceptualization of it will include the possibility of an outside observer
